What can I say except this woman can be as inconsistent as the next man along.
I would HOPE I'm more inclined to go for more than good looks but at the end of the day you if you have to pick something out of the chocolate box of life then sometimes you have to start with outward appearance and try before you decide if the centre is something you like......
So making sure you are clean,smell good,your clothes are clean and decent and you have cleaned your teeth is a pretty good start.
After that you have to remember we are individuals and what may work as a chat up line with some of us may not with the rest of us.It's as much trial and error for us as it is for you.If you remember that the women you are meeting may well be as shy and as awkward as you but better at hiding it it might help you..but then again it may be a turn off.
To be honest it might be helpful if some of you actually think what it is you want.If it's a one night stand well does it matter what we think?If it's for friendship,a life partner or just to widen your social circle then it's as well to widen the places you go to look for women.
And at the end of the day the more rounded you are in personality,interests,knowledge and life skills the more chances you will have.
As for those women who keep picking barstewards and having a bad time..maybe giving them a wide berth..they need to do some growing up first themselves.
